SOLTEC ® Progressive Cavity Single Screw Pump Operation and Design

SOLTEC ® www.soltecpumps.com
The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities which move forward and produce discharge pressure.
The number of the rotor's pitches defines differential pressure of a progressive cavity pump, when volume of the cavities and rotation frequency of the rotor determine flow rate.
The principle of operation of Progressive Cavity Pumps was invented and patented by French aviator René Moineau in 1930. Since that millions of Progressive Cavity Pumps have been manufactured across the globe that have opened new opportunities in many industries.
SOLTEC ® is one of the largest European manufacturers on Progressive Cavity Pumps.
